Coverage

Years of collection, reference years, and sample sizes

Spanish Statistical Institute (INE) in collaboration with the Ministry of Health (since this issue, a homogenized data series has been carried out):
Wave 1 (2003): Data was collected from April 2003 to March 2004. The sample consisted of approximately 22,000 dwellings distributed among 1,844 census tracts.
Wave 2 (2006): Data was collected from June 2006 to June 2007. The sample consisted of approximately 31,300 dwellings distributed among 2,236 census tracts.
Wave 3 (2009): (first wave of the European Health Survey in Spain) Data was collected from April 2009 to March 2010. The sample consisted of approximately 23,000 dwellings distributed among 1,927 census tracts. 22,188 interviews were conducted.
Wave 4 (2011-12): Data was collected from July 2011 to June 2012. Interviews were conducted (in 21,508 households) with 21,007 adults (aged 15 or over) and with 5,495 children aged 14 and under, by interviewing his or her mother, father or guardian. A total of 26,502 interviews were carried out.

First year of collection

1987

Stratification if applicable

A stratified tri-stage sample type is used. The first stage units are census tracts. The second stage units are the main family dwellings. All households whose regular residence is within said dwellings are studied. Within each household, one adult person (aged 15 and over) is selected to complete the individual questionnaire. Where there are children (aged between 0 and 14 years), a minor is also selected to complete the minor questionnaire.
A sample has been selected of approximately 24,000 dwellings distributed among 2,000 census tracts. The sample is distributed among Autonomous Communities (Spanish regions), assigning one portion uniformly and another in proportion to the size of the Autonomous Community, such that, besides being representative at a national level, it is also representative at an Autonomous Community level, at least for the main variables.
Ratio estimators have been used to estimate all population characteristics. Re-weighting techniques have been applied to them, taking as auxiliary variables age groups, sex and nationality of the population of each Autonomous Community.

Base used for sampling

Sample is extracted from Municipal Register by the Population Unit database

Geographical coverage and breakdowns

National data, Regional data (NUTS 2 breakdown)

Age range

Depending on variables, the whole Spanish population in 2011-12, minors (aged 14 and under) and adults (aged 15 and over).

Statistical representativeness

NUTS 2 [Autonomous Community breakdown]

Coverage of main and cross-cutting topics

Main topics covered:
National Health Survey allows a detailed study of the following items:
I. Health status and accident rate: perceived health status, chronic or long-term evolution problems, quality of life related to health, limitation of activities due to health problems, accidents, restriction of habitual activities due to health problems, hearing difficulties, vision problems and mental health.
II. Health care: medical consultations (time elapsed since the last visit, average number of consultations, place, reasons, etc.), consultations to the dentist (idem), hospital admissions, emergencies service, inaccessibility to medical assistance, health care coverage [public/private], drugs and medicines consumption, preventive health.
III. Health determining factors: Tobacco and alcohol consumption, body mass index, physical activity, special diet, consumption pattern of certain foods, social support received, care of children or persons with any limitations.
- Residential and social environment.
- Social, economic, demographic and geographical features (sex, age group, social class based on the occupation of the reference person, country of birth, Autonomous Community (Spanish regions), educational level and current relationship with the economic activity.
Statistical tables of the health variables researched are provided, classified by the following socio-demographic characteristics: sex, age group, social class based on the occupation of the reference person, country of birth, Autonomous Community (Spanish regions), educational level and current relationship with the economic activity.
The general aim of NHS 2011-2012 is to provide the necessary information on the health of the population in order to be able to plan and assess actions on health issues. It is designed for:
1. Providing information regarding the assessment of the general state of both physical and mental health and identifying the main health problems faced by citizens: chronic illnesses, ailments, accidents and functional limitations.
2. Ascertaining the degree of access to and use of health services.
3. Ascertaining the determining health factors: lifestyle habits and characteristics of the physical and social environment that pose a health risk.
4. Analysing the differences with which health problems are faced, the risk factors and the use of services among the different population subgroups (by sex, age, social class, country of origin, studies, economic activity and Autonomous Community).
The survey has three questionnaires: A Household Questionnaire, an Adults Questionnaire with +150 questions, and a Minors Questionnaire with 80 questions. The method used to collect information is with a computer-assisted personal interview (CAPI), directly in the case of adults, and in the case of children aged 14 and under, the mother, father or guardian answers on behalf of the minor.
The questionnaire consists of four large blocs: socio-demographic, health status, health care and health determining factors.

A sample has been selected of approximately 24,000 dwellings distributed among 2,000 census tracts. The sample is distributed among Autonomous Communities (Spanish regions), assigning one portion uniformly and another in proportion to the size of the Autonomous Community, such that, besides being representative at a national level, it is also representative at an Autonomous Community level, at least for the main variables.
Ratio estimators have been used to estimate all population characteristics. Re-weighting techniques have been applied to them, taking as auxiliary variables age groups, sex and nationality of the population of each Autonomous Community.

Base used for sampling

Sample is extracted from the Municipal Register by the Population Unit database

Geographical coverage and breakdowns

National data, Regional data (NUTS 2 breakdown)

Age range

Depending on variables, the whole Spanish population in 2011-12, minors (aged 14 and under) and adults (aged 15 and over).

Statistical representativeness

NUTS 2 [Autonomous Community breakdown]

Coverage of main and cross-cutting topics

Main topics covered:
National Health Survey allows a detailed study of the following items:
I. Health status and accident rate: perceived health status, chronic or long-term evolution problems, quality of life related to health, limitation of activities due to health problems, accidents, restriction of habitual activities due to health problems, hearing difficulties, vision problems and mental health.
II. Health care: medical consultations (time elapsed since the last visit, average number of consultations, place, reasons, etc.), consultations to the dentist (idem), hospital admissions, emergencies service, inaccessibility to medical assistance, health care coverage [public/private], drugs and medicines consumption, preventive health.
III. Health determining factors: Tobacco and alcohol consumption, body mass index, physical activity, special diet, consumption pattern of certain foods, social support received, care of children or persons with any limitations.
- Residential and social environment.
- Social, economic, demographic and geographical features (sex, age group, social class based on the occupation of the reference person, country of birth, Autonomous Community (Spanish regions), educational level and current relationship with the economic activity.
Statistical tables of the health variables researched are provided, classified by the following socio-demographic characteristics: sex, age group, social class based on the occupation of the reference person, country of birth, Autonomous Community (Spanish regions), educational level and current relationship with the economic activity.
The general aim of NHS 2011-2012 is to provide the necessary information on the health of the population in order to be able to plan and assess actions on health issues. It is designed for:
1. Providing information regarding the assessment of the general state of both physical and mental health and identifying the main health problems faced by citizens: chronic illnesses, ailments, accidents and functional limitations.
2. Ascertaining the degree of access to and use of health services.
3. Ascertaining the determining health factors: lifestyle habits and characteristics of the physical and social environment that pose a health risk.
4. Analysing the differences with which health problems are faced, the risk factors and the use of services among the different population subgroups (by sex, age, social class, country of origin, studies, economic activity and Autonomous Community).
The survey has three questionnaires: A Household Questionnaire, an Adults Questionnaire with +150 questions, and a Minors Questionnaire with 80 questions. The method used to collect information is a computer-assisted personal interview (CAPI), directly in the case of adults, and in the case of children aged 14 and under, the mother, father or guardian answers questions on behalf of the minor.
The questionnaire consists of four large blocs: socio-demographic, health status, health care and health determining factors.

Data quality

Entry errors if applicable

To analyze the lack of response from the National Health Survey 2011-2012, a questionnaire was designed to assess the lack of response. Information was collected on the basic characteristics of the units that failed to cooperate in the survey, i.e. data on housing and household inhabitants, household characteristics (size and type), and some characteristics of the reference person (sex, age, marital status, education level, relationship with the activity and nationality). The questionnaire was completed for target households due to refusal, absence or inability to answer.
A series of measures have been implemented to help ensure the quality of the process and the results, such as:
- Specific revision of the questionnaire in a working group to introduce new internationally validated instruments
- Data collection through a CAPI application to detect errors and warnings on incompatibility or inconsistency between the survey responses.
- Periodic inspection fieldwork.
- Housing replacement in non-response situations to ensure a sample closer to the population structure.
- Comprehensive review of the codifications of some sensitive questions.
- Handling errors and warnings after collection in order to confirm correctness and prevent systematic errors.
